How a User Equipment decodes the received beam from beamforming? Can UE generate beams to send data from UE to Base Station?

UE knows which precoding was used for construction of that beam. Then data is retrieved from DM-RS demodulation.
Yes, to generate narrow beams you need more antennas though. So real “beams” are particularly visible in case of UE communicating on FR2 (mmWave bands).
